In the laboratory a "coffee cup" calorimeter, or constant pressure calorimeter, is frequently used to determine the specific heat of a solid, or to measure the energy of a solution phase reaction. Thermometer Stirring rod A student heats 62.12 grams of platinum to 98.69 °C and then drops it into a cup containıng 78.31 grams of water at 23.37 °C. She measures the final temperature to be 25.15 °C. The heat capacity of the calorimeter (sometimes referred to as the calorimeter constant) was determined in a separate experiment to be 1.66 J/°C. Water Assuming that no heat is lost to the surroundings calculate the specific heat of platinum. Metal sample Specific Heat (Pt) = Jg°C.

Question
In the laboratory a "coffee cup" calorimeter, or constant pressure calorimeter, is frequently used to determine the specific heat of a solid, or to measure the energy of a solution phase reaction. Thermometer Stirring rod A student heats 62.12 grams of platinum to 98.69 °C and then drops it into a cup containing 78.31 grams of water at 23.37 °C. She measures the final temperature to be 25.15 °C. The heat capacity of the calorimeter (sometimes referred to as the calorimeter constant) was determined in a separate experiment to be 1.66 J/°C. Water Assuming that no heat is lost to the surroundings calculate the specific heat of platinum. Metal sample Specific Heat (Pt) =| Jg°C. 2es T sCole In the laboratory a "coffee cup" calorimeter, or constant pressure calorimeter, is frequently used to determine the specific heat of a solid, or to measure the energy of a solution phase reaction. Thermometer Stirring rod Since the cup itself can absorb energy, a separate experiment is needed to determine the heat capacity of the calorimeter. This is known as calibrating the calorimeter and the value determined is called the calorimeter constant. One way to do this is to use a common metal of known heat capacity. In the laboratory a student heats 96.76 grams of zinc to 98.71 °C and then drops it into a cup containing 80.20 grams of water at 20.80 °C. She measures the final temperature to be 28.61 °C. Water Using the accepted value for the specific heat of zinc (See the References tool), calculate the calorimeter Metal sample constant. The nBrekC Calorimeter Constant = | J/°C.

In the laboratory a "coffee cup" calorimeter, or constant pressure calorimeter, is frequently used to determine the specific heat of a solid, or to measure the energy of a solution phase reaction. A chunk of silver weighing 19.29 grams and originally at 97.46 °C is dropped into an insulated cup containing 79.59 grams of water at 21.22 °C. Thermometer Stirring rod The heat capacity of the calorimeter (sometimes referred to as the calorimeter constant) was determined in a separate experiment to be 1.76 J/°C. Water Metal sample Using the accepted value for the specific heat of silver (See the References tool), calculate the final temperature of the water. Assume that no heat is lost to the surroundings. 2000 Thomaon-Brocks/Cole Tfinal = °C.
